Culture of Candida in vinasse and molasses: Effect of acid and salt addition on biomass and raw protein production

Species of the genera Candida grown in vinasse and molasses were studied under the following conditions: agitation of containers, pH 4.6, culture time of 24 hours at 30°C. The greatest biomass production of C. krusei grown in vinasse was obtained with the addition of 0.1% H₃PO₄, and of C. guilliermondii and C. utilis with the addition 0.02% urea plus 0.03% H₃PO₄. Protein levels near 50% were found in C. utilis in vinasse supplemented either with molasses, with 0.05% MgSO₄, or with 0.02% urea plus 0.03% H₃PO₄.
